The turning radius on a lift truck is also referred to as the turning circle. This information is vital for a machine operator to have. It gives the driver the information of how much space is required to turn the forklift around. Like for instance, a tighter turning radius allows the machine to successfully operate in congested areas and tight places, thus enhancing the maneuverability of the forklift. Operators who are not aware of this measurement may cause damage to the machinery or to the property.
Make the necessary steering geometry alignment corrections prior to testing the turning radius. The test should start with an operator trainer helping in the cab where they can assist to control the equipment's functions. Another individual on the ground uses a hose or a spray bottle to wet the inside and outside of the unit's wheels. After that, drive the machinery in a whole circle with the wheels turned to the maximum angle. Repeat the procedure once and if necessary, continue to wet the wheels.
Measure the watermarks left by the tires utilizing a tape measure once your measurement test has been completed. The watermark test starts from the midpoint of the tire mark to a similar point across the circle's diameter. For the outside turning diameter, measure the watermark left by the outside tires from the circle's one side to the opposite side of the circle. The inside turning diameter can be determined by stretching the tape measure across the circle left by the inner tires. After that, divide these numbers in 2 in order to determine the turning radius. Be sure to note that the turning center is the midpoint of the circle's diameter.
Drop a plumb line from the extreme outside radial extension on the vehicle in order to determine the wall-to-wall turning diameter. When this is accomplished, next locate the point on the pavement directly below. This point to the turning center indicates the clearance radius of the machine. As a rule, wall-to-wall turning diameter is twice the equipment clearance radius.
